I’m trying to convince the maintainers of the NiX Spam DNSBL to add a DNS TXT resource record timestamp to their zone, so that we can monitor zone slaves for freshness. The simple diagram (created with Penultimate while explaining to a colleague) shows what I’ll do with it. I’ve got the check program ready, and I do hope they’ll adopt my suggestion. :-)
